Jackson's eclectic trip to the UK also includes an appearance at a division three football ground and a party being held in his honour by fans.

The visits clearly go against his usual behaviour, that of reclusive international superstar.

But there are question marks about whether his career has suffered because of this.

Scepticism

So is hitting the UK for a whirlwind visit to the UK a tactical ploy to get attention or simply an opportunity for him to help a charity and thank his fans at the same time?

Geller has invited Jackson to attend a charity event being held at Exeter City Football Club, where he will be made an honorary director.

And unsurprisingly, some said it was all a hoax.

Jackson is used to filling giant stadia around the world, yet not all the tickets for the 10,000-seat event have been sold.

But there is no doubt his star has faded in recent years. There must be a desire to resuscitate his career and going back to grass roots promotion would seem a good place to start.

Ulterior motive

But fans do not share the scepticism about the motives behind Jackson's UK visit.

"I believe he is in the UK to carry out two things that are closest to his heart; helping a children's charity and thanking his fans for their support since the last album," Gloria Haydock, president of the Michael Jackson News International fan club, told BBC News Online.

"He has nothing to promote because effectively the last album has been killed off, so there is no ulterior motive behind it."

Jackson holds the record for the biggest selling album in world with the 1982 release Thriller, which has sold 47 million copies.

But his elusiveness has also brought about a reputation of not being in touch with the real world.

Charity launch

Jackson is no stranger to UK shores, having visited on several occasions.

But his trips have rarely been run-of-the-mill promotional tours.

In 1999 he was in London as a guest of Harrods proprietor Mohammed Al Fayed.

During his stay, Jackson visited the top London store and Fulham Football Club, where Mr Al Fayed had recently taken over ownership of the London side.

His last appearance in the UK in June 2001 did little to dispel his eccentric reputation as he visited the Oxford Union to launch his charity Heal the Kids.

After much hype, Jackson was three hours late for his appearance, hobbling on crutches after injuring himself.

At the time Jackson was beginning to move into the limelight again as he prepared to launch his first original album in 10 years.

Sidelined

But although eagerly awaited by fans, positive reviews for Invincible were few and far between, with criticisms he had not moved on musically in a decade.

This was reflected in album sales, which reached five million worldwide.

Fans blame Jackson's record company Sony for not doing enough to promote it, effectively accusing it of sidelining him in favour of newer artists.

This started a campaign by fans across the globe, which culminates in a mass demonstration outside Sony's London headquarters on Saturday.

Following the demonstration, a fan party is being held at a London nightclub with Jackson confirmed as the star guest.

Despite the drop in Jackson's popularity there is still a confidence he can once again emulate the popularity of his heyday.

"No-one is denying there are problems with his career but he has survived far worse things and come through it," said Ms Haydock.
